Sensodyne Pronamel Daily Enamel Care Mouthwash helps protect against the effects of acid wear and re-harden enamel. Sensodyne Pronamel Daily Enamel Care Mouthwash is formulated to help protect against the effects of Acid Wear, and also helps protect against tooth decay with twice daily brushing. Dentists have reported a growing dental health concern due to changing modern diets. Acids in everyday food such as orange juice and wine can dissolve minerals from our teeth, softening the enamel surface which can then be more easily worn away.
